MALWARE TO TARGET HARRY POTTER FANS
Can't wait to see "Harry Potter and the Half-Blood Prince"? Thinking about downloading a pirated copy? Think again, as it could contain malware.
Cybercriminals are pushing "blackhat" search engine optimization tactics to target the most popular file sharing and P2P networks, pursuing those interested in upcoming movie releases and in particular taking advantage of the sizeable Harry Potter fan base wanting to download the movie in advance of its screening.
Fans are baited with text like: 'Watch "Harry Potter and the Half-Blood Prince" online free'. What appears to be a legitimate looking website then redirects you to a video offer which prompts you to download and install the additional "streamviewer". The streamviewer, however, is installing malware. Suddenly, missing out on a sneak peek is the least of your worries!
To stay protected, remember to run Smart Updates regularly and download movies only from trusted online retailers.
